I'm having hair and makeup done on site and have already had 3 people express that they thought they should go second to last due to their role in the wedding, which is ridiculous. Now I feel like people see the hair/makeup order as a representation of whom I like the most. I want some objective way of figuring this out e.g., the hair stylist said its best to go in order of hair length or something similar that takes this out of my hands. Or can I have everyone just show up at the same time and let it work itself out? How did you choose order?
